PURPOSE: To comprehensively and automatically control the dehumidification of a green house for protected horticulture with an air-conditioning dehumidifier, a fan-forced heater, curtains and skylights for 24hrs every day. CONSTITUTION: A dehumidification controller 10 for dehumidifying a green house 1 in which heat-insulating curtains 2, skylights and a fan-forced heater 23 are disposed contains a composite controller 11, a curtain controller 12 and a skylight controller 13. The inner room temperature and inner humidity of the green house are inputted into the composite controller from a room temperature sensor 24 and a humidity sensor 25, respectively. The composite controller outputs signals to the curtain controller 12, the skylight controller 13 and the fan-forced heater 23, respectively, in response to the room temperature and room humidity based on the inputted data. On the basis of the signals, the heat-insulating curtains 2 and the skylight 3 are opened or closed, and the fan-forced heater is switched on or off. |
